SQL action result in a presentation as string not array

Hi All,

I have a simple action with a SQL query where I get an array as result and which I use in a couple of workflow.

What I need now is also an action with a SQL query but as result is a string needed which I can define as "Default value" in the workflow presentation.

Here is the action which I have already with a result of Array/string

//database is input of Type SQL:Database

// table is input of Type SQL table

var currentUsersVMs = new Array();

//get the displayName of the workflow starter

try {

var jdbcConnection = new JDBCConnection();

var connection = jdbcConnection.getConnection(database.connectionURL, database.username, database.password);

System.debug("...connection successful");

var selectStatement = connection.createStatement();

//adjust with your column names to get a string like

//SELECT "Server Name" FROM "yourTable" WHERE "user" = "Karl Mustermann"

var selectString = "select SRV_Name from dbo.VC_Info_All where POWERSTATE = 'On' ORDER BY SRV_NAME";

System.debug("Executing query: " + selectString);

var resultSet = selectStatement.executeQuery(selectString);

// depending if you expect users with no VMs

//if (!resultSet) throw "No rows found in table '" + table.name + "'";

while (resultSet.next()) {

//resultSet columns start a 1!

currentUsersVMs.push(resultSet.getStringAt(1));

}

} catch (exception) {

throw "Error reading from database: " + exception;

} finally {

    try { if (resultSet != null) resultSet.close(); } catch (e) {};

    try { if (selectStatement != null) selectStatement.close(); } catch (e) {};

    try { if (connection != null) connection.close(); } catch (e) {};

}

System.debug("VMs for current User: " + currentUsersVMs);

//for action:

return currentUsersVMs;
